Re: A89: Re: Fw: TI-89 ROM 1.05 vs 2.00 version inquiries
It is possible to make the programs work on both of the calculators. Xavier
shows us that this can be done with the latest DoorsOS. Programmers who
want a wider audience can limit their programs so that it will run on each
calc. As it is right now, I think that the only things of importance to
worry about are the keyboard array and the LCD planes of greyscale. I am
sure that there are other differences, but I think them minor compared to
these two.
